EAR-PHONE ATTACHMENT.

Application filed January 23, 1925.

To all whom it may concern:

Be it known that I, JOHN E. \Voon, a ciri zen of the United States,residing at Pitts field, in the coanty of Berkshire and Stats oi:Massachusetts, have invented certain new and useful Improvements inEar-phone At iachments, of which the following is a specincation.

This invention relates to ear-phone at tachnients and is particularlyadapted for radio uses.

The primary object of my invention is to provide a light, simple,compact, quick detachable attachment for the conventional car-phones nowcommonly used in radio for the purpose of excluding to a certain extent,if desired, external sounds.

A further object of my invention is to provide a compressible cushionaround the outside of the periphery of the attachment which contactswith the head of the user to thereby prevent the so-called radio rashoccasioned by the use of the ordinary earphone.

Still another feature of the invention resides in the fact that theattachment is so constructed that the compressible cushion aforesaid issituated in such a manner as to completely surround the ear of the userto thereby prevent the ingress of foreign noises.

Still another and important feature of the invention is the fact thatthe ear-phone attachment contemplated by my invention spaces theear-phone diaphragm from the war of the user a considerable distance toavoid the disagreeable and harmful results on the ear of the user, dueto static conditions of the air or the condition of the phone.

In the accompanying drawing:

Fig. 1 is a view in front elevation of my attachment.

Fig. 2 is a View in rear elevation of the same, and

Fig. 3 is a view, partly in section, of my invention attached to anordinary earphone.

Referring now more particularly to the drawing, wherein like referencecharacters represent like parts, 1 designates the earphone attachmentgenerally, which is made of any suitable material, but preferablyaluminum because of its lightness, 2 designates an annular outstandingcollar adapt Serial No. 4,286.

it will be apparent to those skilled in the art that by virtue thepeculiar formr'ion the drawing, of my application t simple constructionis prowas i i fun iions of spacing phragin, providing :i ct with thehead of the user and or sin-re riding the entire ear of when in n forthe purpose of pre annoyance b conversation of others oi F never, theattachdoe bdi'lj.) exclude externai s, such as conversation directed atthe rser it will be obvious that my a tachinent provides an insulationbetween the receiver and the shuil of the head, and those harsh sounc ito the static conditions or tuning t other receivers are much lessannoying aithough the actual program being listened to is loud andclear.

Haring thus described my what I claim is:
